Answer:
16 times
Step-by-step explanation:
difference in area = area of bigger circle / area of smaller circle
Area of a circle = πr²
r = radius
imagine the radius of the smaller circle = 1
Area of circle in terms of π= π
radius of the bigger circle = 4 x 1 = 4
Area of bigger circle in terms of π = π4² = 16 π
16 π / π = 16 times

Steve has a hammer that is 0.29 meters long. Which expression is equal to the length, in meters, of Steve's hammer?
Answer:
x = 0.29 m
Step-by-step explanation:
Given :
The length of the hammer is = 0.29 m
The hammer is a tool that may be used in various operation or work by mechanics, plumbers, or masonries and even by normal people.
So let the length of the hammer be x.
The length of the hammer is expressed in meters or inches or centimeters.
Therefore, the expression of length of the hammer is expressed as x = 0.29 m.

The mean of the 5 data is 51.
(55 + 60 + 35 + 90 + x) ÷5 = 51
(240 + x) ÷5 = 51
240 + x = 255
x = 15
10.
The mean of the 5 data is 127.
(100 + 112 + 98 + 235 + x) ÷5 = 127
(545 + x) ÷5 = 127
545 + x = 635
x = 90
12.
The mean of the 5 data is 40.
(34 + 56 + 45 + 29 + x) ÷5 = 40
(164 + x) ÷5 = 40
164 + x = 200
x = 36

what is the distance from (-4, -7) to (4, 8) ?
Answer:
17
Step-by-step explanation:
We can use this formula:
[tex]\sqrt{(x2-x1)^2 + (y2 -y1)^2}[/tex] where x and y indicate the coordinates of the two points
[tex]\sqrt{4-(-4)^2 + (8-(-7)^2} = \sqrt{64 + 225} = \sqrt{289} = 17[/tex]
Answer:
17
Step-by-step explanation:
You are given two points so you use the distance formula
[tex] \sqrt{( {x 2 - x1)}^{2} + ( {y2 - y1)}^{2} } [/tex]
Substitute your points into the formula
What is closure property ?
Answer:
In mathematics, a set is closed under an operation if performing that operation on members of the set always produces a member of that set. For example, the positive integers are closed under addition, but not under subtraction: 1 − 2 is not a positive integer even though both 1 and 2 are positive integers.

37.23-21.25=15.98
There are two labeled weights of 4 grams and 12 grams the tree circles have the same weight what is the weight of each circle in grams
Answer:
The answer is below
Step-by-step explanation:
Let x represent the unknown weight of each of the circles, since there are three of those type of circles, hence the unknown weight is 3x.
From the diagram, the sum of the total weight at one side must be equal to the sum of the total weight at the other side so that they can be balanced, hence:
3x + 4 = 12
subtracting 4 from both sides:
3x + 4 - 4 = 12 - 4
3x = 8
Dividing through by 3:
3x/3 = 8/3
x = 8/3
The weight of each of the circle is 8/3 grams
write the following from least to greatest. 1/8, 2/4, 8/4, 3/15, 2whole 2/7, 20/10
Answer:
Step-by-step explanation:
Convert each number to its decimal equivalent for easier comparison with the other numbers:
1/8 = 0.125 1 (smallest)
2/4 = 0.50 3
8/4 = 2.0 4
3/15 = 0.20 2
2 2/7 = 2.28 6 (largest)
20/10 = 2.00 5 (next to largest)
The smallest number is 1/8 (see above), and the largest is 2.28 (2 2/7).

O logarithmic
O quadratic
O exponential
O linear
Answer:
Linear
Step-by-step explanation:
The type of function which is represented in the table is quadratic, the correct option is B.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
We are given that;
The table
Now,
Looking at the table, we can see that each input value is paired with only one output value, so the relationship is a function. We can also see that the difference between the output values is not constant, so the function is not linear. The quotient of the output values is not constant either, so the function is not exponential. The quotient of the output values does not change in a predictable way, so the function is not logarithmic.
Therefore, by the function the answer will be quadratic.
